<h4><a name = "tag_001_014_1897">&nbsp;</a>NAME</h4><blockquote>
rmdel - remove a delta from an SCCS file (<b>DEVELOPMENT</b>)
</blockquote><h4><a name = "tag_001_014_1898">&nbsp;</a>SYNOPSIS</h4><blockquote>
<pre><code>

rmdel -r <i>SID file</i>...
</code>
</pre>
</blockquote><h4><a name = "tag_001_014_1899">&nbsp;</a>DESCRIPTION</h4><blockquote>
The
<i>rmdel</i>
utility removes the delta specified by the SID
from each named SCCS file.
The delta to be removed must be the most recent delta
in its branch in the delta chain of each
named SCCS file.
In addition, the SID specified must not
be that of a version being edited for the purpose of
making a delta; that is, if a
<i>p@file</i>
(see
<i><a href="get.html">get</a></i>)
exists for the named SCCS file, the SID specified must not
appear in any entry of the
<i>p@file</i>.
<p>
Removal of a delta is restricted to:
<ol>
<p>
<li>
the user who made the delta
<p>
<li>
the owner of the SCCS file
<p>
<li>
the owner of the directory containing the SCCS file.
<p>
</ol>
</blockquote><h4><a name = "tag_001_014_1900">&nbsp;</a>OPTIONS</h4><blockquote>
The
<i>rmdel</i>
utility supports the <b>XBD</b> specification, <a href="../xbd/utilconv.html#usg"><b>Utility Syntax Guidelines</b>&nbsp;</a> .
The following option is supported:
<p>
<dl compact>

<dt><b>-r&nbsp;</b><i>SID</i>
<dd>Specify the SCCS identification string ( SID )
of the delta to be deleted.

</dl>
</blockquote><h4><a name = "tag_001_014_1901">&nbsp;</a>OPERANDS</h4><blockquote>
The following operands are supported:
<dl compact>

<dt><i>file</i><dd>A pathname of an existing SCCS file or a directory.
If
<i>file</i>
is a directory,
<i>rmdel</i>
behaves as though each file in the directory were
specified as a named file,
except that non-SCCS files
(last component of the pathname does not begin with
<b>s.</b>)
and unreadable files are silently ignored.

If a single instance
<i>file</i>
is specified as -,
the standard input is read;
each line of the standard input is taken to be the name of an SCCS file
to be processed.
Non-SCCS files and unreadable files are silently ignored.

</dl>
</blockquote><h4><a name = "tag_001_014_1902">&nbsp;</a>STDIN</h4><blockquote>
The standard input is a text file used only when the
<i>file</i>
operand is specified as -.
Each line of the text file is interpreted as an SCCS pathname.
</blockquote><h4><a name = "tag_001_014_1903">&nbsp;</a>INPUT FILES</h4><blockquote>
The SCCS files are files of unspecified format.
</blockquote><h4><a name = "tag_001_014_1904">&nbsp;</a>ENVIRONMENT VARIABLES</h4><blockquote>
The following environment variables affect the execution of
<i>rmdel</i>:
<dl compact>

<dt><i>LANG</i><dd>Provide a default value for the internationalisation variables
that are unset or null.
If
<i>LANG</i>
is unset or null, the corresponding value from the
implementation-dependent default locale will be used.
If any of the internationalisation variables contains an invalid setting, the
utility will behave as if none of the variables had been defined.

<dt><i>LC_ALL</i><dd>
If set to a non-empty string value,
override the values of all the other internationalisation variables.

<dt><i>LC_CTYPE</i><dd>
Determine the
locale for the interpretation of sequences of bytes of text data as
characters (for example, single- as opposed to multi-byte characters
in arguments and input files).


<dt><i>LC_MESSAGES</i><dd>
Determine the locale that should be used to affect
the format and contents of diagnostic
messages written to standard error.

<dt><i>NLSPATH</i><dd>
Determine the location of message catalogues
for the processing of
<i>LC_MESSAGES .
</i>

<i>file</i>,
a temporary
<i>x@file</i>,
as described in
<i><a href="admin.html">admin</a></i>,
may be created and deleted;
a locking
<i>z@file</i>,
as described in
